CHARLES SPIELMAN, or RICHMOND HILL, NEW YORK, ssreuon ro M. 1;. some &COMPANY, me, on NEW YORK, n. Y.,A CORPORATION on NEW YORK PRINTERSNUMBERING MACHINE My invention relates to numbering machines adapted tobe locked in type forms used by printers and in which the numbers areautomatically changed by the pressure of each impression and it is myobject to produce a device in which the frame will be sturdy, rigid andstrong, which can be quickly and easily machined and in which the typewheels may be easily interchanged. Also to provide a long wearing,easily replaced stop for the plunger and to provide the plunger with along spring which will have a greatly increased life over the shortsprings now in use.

In the drawing Fig. 1 is a side view of the assembled frame; Fig. 2 anend view of the frame, partly broken away; Fig. 3 a top View of theframe; Fig. 4 a sectional view of the structure of Fig. 1 on the line Hthereof; Fig. 5 a bottom view of the frame; Fig. 6 a side view of theassembled device, partly in section; Fig. 7 a view of the end plate;Fig. 8 a side view of the plunger; Fig. 9 a side view of the plungershowing the stop and spring; Fig. 10 a sectional view of the structureof Fig. 9 on the line 10-10 thereof; Fig. 11 a bottom view of theplunger; Fig. 12 an end View of the device; Fig. 13 a sectional viewshowing the frame in the shaft; Fig. 1 1 a sectional View through a typewheel and shaft; Fig. 15 a view of the shaft; and Fig. 16 a view of amodified shaft end.

The frame is made in two parts. The part 1 has the base 2, provided withthe notches 3 and 4:, near one end, the central opening 5 and theupstanding end wall 6. This end wall is provided with a shaft bearing 7and a lock screw hole 8. The edge of the base 2 has a recess 9 to holdthe spring comb holding the pawls in place.

The member 2 of the frame has a slot 10 cut in it leaving the side andend walls 11, 12 and 13. The end wall has a shaft bearing 1 1 in it andthe side walls 11 and 12 each has a depending lug 15 and 16 on itsbottom edge. One side, bottom bar 17 is milled to the arc of a circle asbest shown in Fig. 1, preferably by running a milling tool in endwise,to give clearance to the type wheels.

The frame is assembled by inserting the lugs 15 and 16 into the notches3 and 4 and peening the exposed ends over thebase. The

two parts may also be sweated together so that they become an integralstructure. This results in a solid, 'rigidframe.

The plunger 20 shown in Figs; 8, 9,10 and 11, has a side out 21 toengage an operating lever and a bore 22 as, a spring seat. The plungerhas two holes 23-24 drilled into it to receive the edges of the stostaple 25. The end plate 26 has an opening 2 and guide pins 28 enteringapertures in the frame as shown in Fig. 1. The long spring 29 isinserted in the seat 22 and the plunger inserted into the space betweenthe walls 11, 12 and 13 after which the cover plate 26 is screwed intoplace with the stop in the opening 27. This permits the plunger to riseand fall with each impression, the upper end of the opening acting as astop on the up movement and the lower end of the opening acting as astop to hold the plunger in the printing plane when down.

The numbering wheels and operating mechanism therefor are of the usualtype and.

form no part of the presentinvention. The shaft, however, is made insuch manner that the wheels may be easily removed and replaced ifdamaged, or where skip numbering is desired.

The shaft 30 has the usual slot 31 to receive the drop 0 characters onthe type wheels as best shown in Fig. 14. The inner end of the shaft isreduced in diameter at 32 to enter the bearing 14 in the end wall 13,the shoulder on the shaft fitting solidly up against the face of the endwall and rigidly holding the inner end of the shaft in position. Theouter end of the shaft has a; flat face 33, provided with a slot 34and'the end of the shaft has a second slot therein.

The type wheels are assembled on the shaft,

in the frame, in the usual manner and the and no way to push the shaftout from the other end of the machine. This slot 34 may take the form ofa raised lip 36 as shown in Fig. 16.

By this construction a simple, easily assembled and disassembled deviceis produced Which has long wearing qualities. The stop staple may beeasily replaced when worn, the spring may be easily replaced When Weakand the type wheels e'asilyreplaced as desired. we

I claim: r

A printers numbering machine comprising a frame provided with anaperture in an end Wall, type Wheels in said frame, means for movingsaid type Wheels, a plunger in said frame adjacent the apertured end foractuating the type moving means, said lunger being provided with a boreextend- 1ng substantially its entire length, an actuating spring in saidbore, said plunger being provided with two holes adjacent the frameopening, and a stop staple in said holes, the head of which extends intothe frame opening and slidable therein With the plunger.

In testimony whereof I have aflixed my signature. i 7 CHARLES SPIELMAN.
